custom permalinks (clean up and change urls)

There is a way to use permalink URLs with My Calendar, but it’s not very easy, right now. You’d need to enable post permalink targets for the events:

add_filter( 'mc_use_permalinks', 'my_custom_event_links' );
function my_custom_event_links( $default ) {
   return true;
}

After doing that, there would likely be some styling to do to make that work ideally for you.

Thank you for reply. How and where can I “enable post permalink targets for the events” ?

That is how you’d enable them; by adding that code either as a custom plug-in, or to your theme’s functions.php file.

Do you have a premium version available for purchase? If not, do you plan on releasing premium version offering custom permalink URLs with My Calendar? If yes please let me know, Im ready to buy asap ??

Not right now; but it’s targeted for June or July release.
